UNVENTED HOT WATER CYLINDERS
STORAGE PRIOR TO INSTALLATION
EVERFLO STAINLESS UV should be stored in its original packaging
in an upright position in an area free from excessive damp.
Regulations G3+L.
HANDLING PRODUCT
The EVERFLO STAINLESS UV should be carried upright where
possible. Assessments of risks for carrying the cylinder should
be conducted. Use more than 1 person for carrying where
appropriate. Always follow latest guide lines for lifting techniques,
to avoid injury and damage to the product.
WATER SUPPLY
EVERFLO STAINLESS UV operates at 3 bar (controlled by the inlet
control set) and is capable of delivering over 50 litres per minute.
The high quality inlet control set has been designed to make the
most of the ow rates available, however the performance of any
unvented system is only as good as the mains water supply. The
maximum possible water demand should be assessed, taking
into consideration that both hot and cold services are supplied
simultaneously from the mains.
The water supply should be checked to ensure it can meet these
requirements. If necessary, consult the local water company
regarding the likely pressure and ow rate availability.
If measuring the water pressure, note that a high static (no ow)
mains pressure is no guarantee of good ow availability. In a
domestic installation 1.5 bar and 25 l/min. should be regarded as
the minimum. The maximum mains pressure that the inlet control
set can accept is 12 bar.
Consideration should be given to upgrading existing ½” (15mm)
cold mains pipework to a larger size if the recommended
minimum pressure/ow rate is not being achieved.
ELECTRIC SUPPLY
The EVERFLO STAINLESS UV requires 240 Volt electrical supply for
the standard Incoloy immersion elements. The electrical supply
to each immersion heater must be fused at 13A via a double
pole isolating switch to BS 3456. The cable must be at least
2.5mm2 heat resistant (85°C HOFR) sheathed ex complying to BS
6141:1981 Table 8.

SITTING THE UNIT
EVERFLO STAINLESS UV can supply outlets above it or at some
distance from it. Site the unit to minimise “dead leg” distances,
especially to the point of most frequent use.
Outlets above the EVERFLO STAINLESS UV will reduce the outlet
pressure available by 0.1 bar for every 1m of height dierence. The
unit should be protected from frost. Particular care is needed if
sitting in a garage or outbuilding. All exposed pipework should be
insulated. EVERFLO STAINLESS UV must be installed VERTICALLY
on a at base capable of supporting the weight of the cylinder
when full. See technical specication section (page 27-28) for
weights. The minimum recommended cupboard size is 650mm
square.
NOTES:
The pressure reducing
valve, non-return valve and
expansion relief valve are
combined together in the
inlet control set.
On 60 – 180 litre sizes there
is no dedicated secondar y
return boss and the
secondary return circuit
should be tee’d into the cold
feed pipe just above the
drain elbow.
SCHEMATIC DIAGRAM
Access for maintenance of the valves should be considered.
Consideration should be given to position of discharge pipes
(tundish), drain valves - shall be positioned away from electrical
components.
The immersion heaters are 375mm long and care should be taken
to ensure that they can be withdrawn for servicing if required.
The discharge pipework from the safety valves should fall
continuously and terminate safely.

EVERFLO UNVENTED HOT WATER CYLINDERS
GENERAL INSTALLATION
COLD MAINS PIPEWORK
Run the cold main through the building to the place where the
EVERFLO STAINLESS UV is to be installed. Take care not to run the
cold pipe near hot water or heating pipework so that the heat
pick-up is minimized. Identify the cold water supply pipe and t
an isolating valve (not supplied).
A 22mm BS1010 stopcock can typically be used but a 22mm
quarter turn full bore valve would be better as it does not
restrict the ow as much. Do not use “screwdriver slot” or similar
valves. Make the connection to the cold feed of the cylinder
and incorporate a drain valve. Position the drain valve no higher
than the cold inlet to ensure sucient draining of cylinder when
required. Position the inlet control just ABOVE the Temperature &
Pressure Relief Valve (TPRV) mounted on the side of the cylinder.
This ensures that the cylinder does not have to be drained down
in order to service the inlet control set. Ensure that the arrow
points in the direction of the water ow. Select a suitable position
for the expansion vessel. Mount it to the wall using the bracket
attached to the vessel. Use suitable ttings capable of supporting
full vessel weight (and with appropriate consideration to wall
material). Ensure the pre-charge in the vessel is set at 3 Bar.
Connect the expansion vessel to the cold feed pipework between
the inlet control set and the cold inlet on the cylinder. Ensure that
the top of the vessel is accessible for servicing.
CONNECTING TO THE CYLINDER
All of the pipework connections on the cylinder are 22mm
compression and supplied complete with gland nuts and olives, in
the Accessory Kit box. Only connect 22mm Table X copper tube to
these connections.
Cut the tube with a pipe cutter and ensure no sharp edges or
burrs protrude. Slide both gland nut and olive onto the tube and
push tube fully home into the connection, ensuring the tube
end fully bottoms on the connection recess. Smear the outer
wall of the olive with plumbing paste and tighten gland nut
in the prescribed manner. Upon lling/commissioning, ensure
all connections are completely watertight. Note: No control or
isolation valve should be tted between the expansion relief valve
and the storage cylinder. The relief valve connections should not
be used for any other purpose.

EVERFLO STAINLESS UV
UNVENTED HOT WATER CYLINDERS
BALANCED COLD CONNECTION
If there are to be showers, bidets or monobloc taps in the
installation then a balanced cold supply is necessary. There is a
22mm balanced connection on the inlet set.
HOT WATER PIPEWORK
Run the rst part of the hot water distribution pipework in 22mm.
This can be reduced to 15mm and 10mm as appropriate for the
type of tap etc. Your aim should be to reduce the volume of the
hot draw-o pipework to a practical minimum so that the time
taken for the hot water is as quick as possible. Where monobloc
mixing taps and showers are used, these should be installed to
comply with the Water Supply (Water Fittings) Regulations 1999.
If these devices are supplied with un-balanced supplies there
should be single check valves installed at both inlets, to stop over
pressurising of either supply.
PRIMARY COIL CONNECTIONS FOR INDIRECT UNITS
For Solar input models refer to pages 13-14 before making any
connections.
Connect the primary connections (Indirect only) using the
compression connections provided. The primary circuit must
be positively pumped. Gravity circulation is not suitable. Either
primary connection may be used as the primary ow, reheat times
are not eected. The primary circuit can be open vented or sealed,
with up to a maximum pressure of 3.5 bar. If you seal the primary
circuit an additional expansion vessel and safety valve is required.
The boiler may be Gas, Electric or Oil but must be under eective
thermostatic control. Uncontrolled heat sources such as some
AGA’s, back boilers, solid fuel stoves, etc. are NOT SUITABLE. Please
contact our Technical department for guidance. Connect the two
port zone valve ( indirect only ) into the primary ow pipework.
The direction of ow arrow should be towards the primary ow
connection.
SECONDARY CIRCULATION
EVERFLO STAINLESS UV can be used with secondary circulation.
An appropriate WRAS approved bronze circulator should be
used in conjunction with a non-return valve to prevent backow.
On large secondary circulation systems it may be necessary
to incorporate an extra expansion vessel into the circuit to
accommodate the increased system water volume. Secondary
circulation should be avoided on Direct electrically heated units
being used on o-peak electricity taris.
A secondary return boss is tted as standard on 210, 250 & 300 ltr
units. On smaller sizes, tee into the cold feed pipe above the drain.
IMMERSION HEATERS
Only immersion heaters with a thermal cut-out may be used. To
help ensure this, the immersion heaters have a special 1¾” thread.
They are rated at 3kW at 240V and are of a low noise Incoloy
construction.
They have both a thermostat and a high limit cutout. Please order
the correct replacement via ourselves; tting non-approved
immersions may aect your guarantee. When tting, ensure the
‘O’ ring is positioned correctly on the head of the immersion
heater and lubricate before tting. Fit it by hand until almost
home then tighten gently as the ‘O’ rings will seal easily. The
electrical supply to each immersion heater must be fused at 13A
via a double pole isolating switch to BS 3456. The cable must be
2.5mm
2
heat resistant (85°C HOFR) sheathed ex complying to BS
6141:1981 Table 8. Do not operate the immersion heater/s until the
unit is full of water. Do not operate the immersion heater/s if any
sterilisation liquid is in the cylinder as this will cause premature
failure.
ELECTRICAL CONNECTIONS
Complete the wiring – use the appropriate wiring diagrams on
page 15 - 18.

UNVENTED HOT WATER CYLINDERS
DISCHARGE ARRANGEMENT
Position the inlet control group so that the discharge from both
safety valves can be joined together via a 15mm end feed Tee (see
diagram above). Connect the Tundish and route the discharge
pipe. The discharge pipework must be routed in accordance with
Part G3 of schedule 1 of the Building Regulations. The information
that follows is not exhaustive and if you are in doubt you should
seek advice. The two safety valves will only discharge water under
fault conditions. When operating normally water will not be
discharged. The tundish should be vertical, located in the same
space as the unvented hot water storage system and be tted
as close as possible to, and lower than, the safety device, with
no more than 600mm of pipe between the valve outlet and the
tundish. The tundish should be positioned away from electrical
devices.
Any Discharge should be visible at the tundish. The tundish should
be located such that any discharge is visible. In addition, where
discharges from safety devices may not be apparent, e.g. people
with impaired vision or mobility, consideration should be given to
the installation of a suitable safety device to warn when discharge
takes place, e.g. electronically operated.
Diagram of a typical discharge pipe arrangement (extract from
Building Regulation G3)
Note: The discharge will consist
of scalding water and steam.
Asphalt, roong felt and
non-metallic rainwater goods
may be damaged by such
discharges.
Note: D2 pipe from tundish is
now allowed to be installed in
soil stacks within premises. This
activity is not recommended
by Kingspan as discharge
from T&P may continue for
long periods of time. It is the
installer’s responsibility to
ensure the discharge pipework
can support the discharge for
prolonged periods.
If used follow guidance on
mechanical seal without water
trap given in G3 Building
Regulations.
As discharge can be in
excess of 90
o
C discharge into
plastic pipework is also not
recommended.
08
EVERFLO STAINLESS UV
UNVENTED HOT WATER CYLINDERS
The discharge pipe (D2) from the tundish should:
A) Have a vertical section of pipe at least 300mm long, below the
tundish before any elbows or bends in the pipework.
B) Be installed with a continuous fall of at least 1 in 200 thereafter.
The discharge pipe (D2) from the tundish should be of metal or
other material that have been demonstrated to be capable of
withstanding temperatures of the water discharged.
The discharge pipe (D2) should be at least one pipe size larger
than the nominal outlet size of the safety device unless its total
equivalent hydraulic resistance exceeds that of a straight pipe
9m long i.e. discharge pipes between 9m and 18m equivalent
resistance length should be at least two sizes larger than the
nominal outlet size of the safety device, between 18 and 27m at
least 3 sizes larger, and so on. Bends must be taken into account
in calculating the ow resistance. Refer to diagram 1, Table 1 and
the worked example. An alternative approach for sizing discharge
pipes would be to follow BS6700 Specication for design
installation, testing and maintenance of services supplying water
for domestic use within buildings and their curtilages.
The discharge pipe (D2) should terminate in a safe place where
there is no risk to persons in the vicinity of the discharge.
Examples of acceptable discharge arrangements are:
a. To a trapped gully with the end of the pipe below the xed
grating and above the water seal.
b. Downward discharges at a low level; i.e. up to 100mm above
external surfaces such as car parks, hard standings, grassed
areas etc. are acceptable providing that where children play or
otherwise come into contact with discharges, a wire cage or
similar guard is positioned to prevent contact whilst maintaining
visibility.
c. Discharges at a high level; e.g. in to metal hopper and metal
down pipe with the end of the discharge pipe clearly visible or
onto a roof capable of withstanding high temperature discharges
of water and 3m from any plastic guttering systems that would
collect such discharges.
d. Device to warn when discharge takes place.
WORKED EXAMPLE
The example below is for G1/2 temperature relief valve with a
discharge pipe (D2) having 4 No. elbows and length of 7m from
the tundish to the point of discharge.
From Table 1:
Maximum resistance allowed for a straight length of 22mm
copper discharge pipe (D2) from a G1/2 temperature relief valve is:
9.0m. Subtract the resistance for 4 No. 22mm elbows at 0.8m each
= 3.2m. Therefore the maximum permitted length equates to:
5.8m. 5.8m is less than the actual length of 7m therefore calculate
the next largest size. Maximum resistance allowed for a straight
length of 28mm pipe (D2) from a G1/2 temperature relief valve
equates to: 14m. As the actual length is 7m, a 28mm (D2) copper
pipe will be satisfactory.
